DvG_Devices

Collection of I/O interfaces to communicate with microcontroller boards and laboratory devices, with optional PyQt/PySide multithread support and graphical user-interfaces.

Supports PyQt5, PyQt6, PySide2 and PySide6.

Installation:

pip install dvg-devices

To be able to run the several provided graphical user-interfaces, one has to install an additional Qt-library. This can be either PyQt5, PyQt6, PySide2 or PySide6. My personal recommendation is PyQt5 for Python <= 3.7, and PySide6 for Python >= 3.8. Pick one:

pip install pyqt5
pip install pyqt6
pip install pyside2
pip install pyside6

If you wish to interface with an GPIB device you need to additionally install a Visa backend. See https://pyvisa.readthedocs.io/en/latest/introduction/getting.html

Highlights

  • Class SerialDevice() offering higher-level general I/O methods for a serial device, such as auto_connect(), write() and query().
  • Class Arduino() which wraps around SerialDevice(). In combination with DvG_StreamCommand it allows for automatically connecting to your Arduino(-like) device and for easy serial I/O communication.
  • Class TelnetServerDevice() offering higher-level general I/O methods for e.g. an ESP32 microcontroller.
  • Separate PyQt/PySide interfaces are provided for each of these devices, offering out-of-the-box multithreaded data acquisition and communication. It relies on DvG_QDeviceIO.
  • Ready-to-run PyQt/PySide demos to directly control many of the supported devices with a graphical user-interface.
